Climate moderates potential shifts in streamflow from changes in pinyon-juniper woodland cover across the western U.S.

Abstract (from http://onlinelibrary.wiley.com/doi/10.1002/hyp.11264/abstract): Pinyon-juniper (PJ) cover has increased up to 10-fold in many parts of the western U.S. in the last 140+ years. The impacts of these changes on streamflows are unclear and may vary depending on the intra-annual distribution and amount of precipitation. Given the importance of streamflow in the western U.S., it is important to understand how shifts in PJ woodland cover may produce changes in streamflow across the region's diverse hydroclimates. To this end, we simulated the land surface water balance with contrasting woodland and grassland cover with the Hydrologiska Byråns Vattenbalansavdelning (HBV) model at a 4-km resolution across the distribution of [...]
